I have been recently working on android app development on eclipse and suddenly I find that my package explorer has got blank, I am not able to locate my previous packages and project from eclipse package explorer but I can still locate it on my work-space folder. Please, help me to restore my projects and packages.
Probably you have deleted the project (by default it leaves the source files on your workspace).
Try right-clicking, import Java project, locate your project in your workspace. That should solve the issue.
